PRESS Pass: Mark Shriver

Mark Shriver's new book A Good Man: Rediscovering My Father, Sargent Shriver chronicles the life of Sargent Shriver and attempts to figure out "what it mean[s] to be good."

"There are a lot of great people in Washington, so called great people, men and women, but when the lights go off, they’re not good to the camera crew or to the waitresses at the restaurant," Shriver said in a PRESS Pass interview with David. "Dad was different; he was good, the same to everyone, whether you were the president of the United States or the guy at the gas station."

Sargent Shriver fought a long battle with Alzheimer's that he lost in January of 2011. Mark called the disease, "devastating financially and emotionally," and argued that "as a country, we don't spend enough money trying to find a cure for it."

Mark's father had an impressive career that ranged from U.S. Ambassador to France, to founder of the Peace Corps, to heading up the Special Olympics. However, Mark says that through all that, he remained a man driven by his family and his faith.

"Many politicians or political leaders are using now, faith to separate us, to divide us," but Mark Shriver said his father was different, "He really believed that if you were interested in feeding the poor, clothing the naked that that was, he wanted to work with you."
